The Biomaterials Interfaces program kicks off with the now traditional Biomaterials Plenary Session. This year we are pleased to have presentations from two prominent scientists who will present their cutting-edge research on Materials and Biology for Energy Applications.
BP-SuA: Coupled Phenomena in Biomaterial Systems (ALL-INVITED SESSION)
- Kerstin Blank, Johannes Kepler University, Linz, Austria, “Mechanoresponsive Proteins – from Molecular Mechanisms Towards Applications in Biology and Materials Science”
- Ali Dhinojwala, University of Akron, “Learning from Nature to Tackle Adhesion in Wet and Challenging Conditions”
Nanoscale Science and Technology Division Plenary Session

The Nanoscale Science and Technology Division starts the week with a plenary session featuring a talk from the Nanotechnology Recognition Award winner. Following this talk, we will have our Early Career and Graduate Student competitions. Please join us for these engaging talks on nanoscale science and technology and for a lively discussion during a reception, immediately after the competitions.
NSP1: Nanoscience and Technology Division Plenary Session (ALL-INVITED SESSION)
- Sergei Kalinin, University of Tennessee Knoxville, “Bits to Atoms and Atoms to Bits: Atomic Fabrication in Electron Microscopy”
AVS Member Center
November 6-9, 2023 – 7:00 a.m. – 5:00 p.m.
Oregon Convention Center
B114-115
The Member Center will focus on career-related professional development sessions and provide networking opportunities to all attendees throughout the week. Attendees can stop in at any time to participate in our scheduled events, ask questions about how to access your membership benefits, learn how to get involved or have a place to meet up with other attendees. Be sure to stop in and network in our Member Lounge.
Exhibitor Technology Spotlight (EW)
November 7-8, 2023 – 12:20 p.m.
Oregon Convention Center
Hall A-A1-B, Booth #1003
The Exhibitor Technology Spotlight Sessions will take place in the stage area of the exhibit hall during the technical session breaks on Tuesday and Wednesday. These sessions are free and open to all registered AVS 69 attendees. This is your opportunity to learn about new products, research techniques, and services offered by AVS exhibitors. Each session is followed by a brief Q&A session making it a truly interactive learning experience. After the sessions, you may visit the presenting exhibitors at their booths to further discuss any points that you would like to receive more details on. Come learn how new technology can benefit your research efforts!
EW-TuL: Exhibitor Technology Spotlight Session I
ASTM E-42 and Applied Surface Science Division Joint Workshop:
What New Challenges Come with the Capabilities of HAXPES?
Tuesday, November 7, 2023 – 8:00 p.m.
Hyatt Regency
Deschutes A
We know how to do XPS well, even if it is not always done that way. Join us for an evening community forum discussion on the comparison of the requirements for quantitative studies using HAXPES (through the analysis of peak intensities or of the background) in comparison to traditional laboratory XPS. The applications and use of HAXPES have been increasing due to the greater availability of higher energy X-ray sources in commercial instruments, increased access to synchrotron sources, and to improving quantitative data analysis. This forum will examine the similarities and differences among XPS, synchrotron-HAXPES, and laboratory-HAXPES. As a member of the surface analysis community, we need your input to help us identify the most important issues that individual researchers and the surface community need to address including:
• Requirements for Additional Information for Analysts
• Experimental and Analysis Protocols
• New Standards or Guides such as the Determination of Transmission Functions
Our panel will have representation from industry, academia, and national laboratories. We hope to have a lively discussion focused on ensuring that the high level of surface analysis that our AVS community employs is understood and accessible by the ever-broadening user base of surface analysis techniques.
Panel Moderator – Alex Shard
Panelists: David Cant, Olivier Renault, and Thierry Conard

AVS Quantum Science Workshop on ``Materials & Surface Science of Quantum Sensing``
Sunday, November 5, 2023
2:00 p.m. – 6:00 p.m.
Oregon Convention Center
A107-109
Quantum sensing is an important branch of the recently ongoing revolution towards quantum information science, where the idea is to use quantum mechanical properties of the probe as a very sensitive sensing mechanism. Near term real-world applications include using NV centers in diamond e.g., for biosensing or for providing spatially resolved maps of local magnetic fields in quantum diamond microscopes. At the same time, quantum sensing raises interesting fundamental materials and surface science questions.
From a materials science point of view, it is important to provide deep understanding of what defect/host material combinations are best suited for specific sensing properties, possibly outperforming NV centers in diamond. Developing a proper experimental and theoretical understanding of underlying property-function relationships is critical and immediately connects to high-quality synthesis of the host material and precise fabrication and spacing of the point defects used as the probe.
From a surface science point of view the above questions are exacerbated since, for sensing, a balance needs to be achieved: High sensitivity would favor close proximity of the quantum defect to the surface and, thus, the sample; however, in this case too, noise arises as a problem and is typically attributed to surface defects and differences in screening compared to bulk materials. This can be mitigated by placing the quantum system deeper into the bulk host material, at the cost of reducing sensitivity to the sample. Better understanding of the origin of such noise and how to eliminate these is needed.
In this workshop we aim to bring together materials and surface scientists to discuss the problems above, as well as possible solutions and to present successful contemporary applications of quantum sensing.
